Abstract

The invention discloses low-temperature-resistant and crack-resistant synthetic leather applied to baseballs. The synthetic leather comprises a base cloth and a polyurethane composition, wherein the polyurethane composition comprises the following raw materials in parts by weight: 80-120 parts of modified polyurethane emulsion, 10-15 parts of water, 8-10 parts of N-methylpyrrolidinone, 20-30 parts of organized montmorillonite, 10-12 parts of talcum powder, 18-22 parts of lignocelluloses, 0.4-0.6 part of a high-carbon alcohol fatty acid ester compound, 0.2-0.3 part of silicone emulsion, 7-9 parts of a pigment, 1-1.5 parts of a mildew preventive and 2-3 parts of sodium dodecyl sulfate. The synthetic leather has high low-temperature resistance, high low-temperature crack resistance and high low-temperature impact resistance.

Description

technical field [0001] The invention relates to the technical field of synthetic leather, in particular to a low-temperature-resistant and crack-resistant synthetic leather for baseball. Background technique [0002] Baseball is a kind of ball game which is mainly characterized by hitting a ball with a stick, and is highly collective and antagonistic. It is widely carried out internationally and has a great influence, and is known as "the combination of athletics and wisdom". It is especially popular in the United States and Japan, and it is called "national football". [0003] Baseball is a round cork, rubber or similar material as the center, wound with twine, and then wrapped with two pieces of white horsehide or cowhide with flat threads tightly stitched together. Due to population expansion and increasing social demand, horsehide and cowhide resources are increasingly insufficient and expensive, and the mechanical properties and wear resistance of horsehide and cowhid...
